Get the Sony experian z1 I have a htc one the case won’t last the contract and can’t be replaced, it will look like a kicked can within the year. The Samsung has louder speakers, the screen on the s4 is gorilla glass 4 and is much harder to scratch than the htc, the camera is sharper on the s4. The htc takes better pictures in low light and the zoe function is amazing but that is software not hardware. My htc one is 10 months old and looks every day of it. I’d go with the z1, the video editing is better than zoe, the camera is better by far, the glass is tougher too.
